Chapter Exam Questions
Course Introduction
Oral Pathology is the branch of dental science that focuses on the nature, identification, and management of diseases affecting the oral and maxillofacial regions. This course covers the etiology, clinical manifestations, histopathology, and treatment options for a variety of lesions, infections, developmental anomalies, and neoplasms found within the oral cavity. Students are trained to recognize and differentiate between normal and pathological tissues, understand the underlying biological mechanisms of disease, and integrate this knowledge for effective patient care and diagnosis. The course emphasizes both microscopic and macroscopic perspectives to prepare students for clinical application and further study in oral medicine and surgery.
